As the name suggests, they appear clown-like, having bright orange and white banding with a black outline. They are easy to keep and are known for their bond with anemones. They often dash into the tentacles of anemones using them as a safe haven from predators. Wild Clownfish have a mucus preventing the anemones from stinging. Captive bred fish may not have the mucus although this does not seem to limit their friendship with the anemone.
